MACHINE FOR PAINTING BOBBINS, 80C.

QPEGIPICATION forming part of Letters Patent No. 338,380, dated. March23,1886.

Application filed June 1!) 1885. Serial No. 169,251. No model.)

and State of New Hampshire, have invented certain new and usefulImprovements in Machinery for Smoothing and Painting Spools, Bobbins,and other Articles, of which the following is afull and exactdescription.

This invention, while it may be used for smoothing and painting handlesand other articles, is more especially designed for smooth ing andpainting spools and bobbins, such as are used in the-manufacture ofcloth, and I shalil here describe it more particularly as so use Itsobject is in part the same as that of apparatus for painting and dryingbobbins, &c., secured to me by Letters Patent N 0. 296,506, dated April8, 1884, and it resembles said apparatus inasmuch as the spools arepainted by means of a mechanically-driven rotary paintbrush; but thisinvention is different in many respects, and may be used not only forpainting, but for smoothing the articles before the paint is applied.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a side View of the entire machine. Fig. 2 isaverticalcross-section showing the rotary paint-brushes as arranged for paintingspools. Fig. 8 is a partial horizontal cross-section on the line of theprojecting arms or brackets C. Fig. 4 is a partial verticalcross-section showing paint-brush as used in painting bobbins, handles,&c.; and Fig. 5 is a partial side View of machine as used in smoothingthe same.

Thestandards B B, having projecting arms or brackets O, and theadjustable hangers s 8, form the frame-work of the machine. The mainframe B B supports the shaft D. The brackets G 0 support the shaft L,and in the hangers s 8 turns the shaft P. To each of said shafts powermay be applied in any convenient manner. The movement of each part ofthe machine is in the direction indicated by arrows.

On the shaft D, and turning with it, is fixed a circular drum orcarrier, A, having its ends enlarged in the form of flanges or heads HH. Said heads have indentations 0 made in their circumferences at equalintervals, their number and relative position being the same in bothheads. On each side, and extending below each of the indentations, amortise, the outline of which is shown in Fig. 1 by the dotted line :0w, is made to receive the anti-friction rollers h h, pivoted at z. Thecircumferences of said rollers extend into the indentations c, on eitherside, as shown at It, Fig. 1.

Between the heads H H of the drum A, and so placed as not to interferewith the working of the rollers h h, other and longer rollers are fixed,as at a a, Figs. 2, 3, and 4, and shown in dotted line (1, Figs. 1 and5. Said rollers have bearings in both the flanges or heads H H, and thebearing on one end of roller projects through and beyond the flange inwhich it turns, forming spindles or mandrels b b.

Upon or between each set of the anti-friction rollers h his placed aspool, S, which, although it is firmly supported by them, is allowed torotate freely, when, by the revolution of the drum or carrier A it isbrought in contact with the friction-belt K K K K. Said belt, in thepresent instance, is driven from a shaft above the machine, and isflexed out of its natural course by means of the pulleys 0 o 0 0, thuspartly encircling the drum A. Said belt is held in frictional contactwith whatever articles are supported by the rollers h h by means of thepulley 0, which is sup ported by theframe F, hung loosely on the rod 1*.Said pulley and frame exert their combined weight as a tightener uponthe belt K K K K, drawing it firmly against said articles, and alsoserving to bring the friction-belt in contact with the rollers a a, whenthere are no spools or other articles upon the anti-friction rollers hh. Vhile being rotated by the friction-belt K K K K the revolving drumor carrier A brings the spools or other articles,

S, into contact with the smoothing-wheels E 93 IOO with some erosivematerial, in order to polish or smooth the surfaces of the work beingfinished as it passes between them, as shown at S, Fig. 3. .After beingsmoothed by passing between the wheels or rubbers as above described thespools or other articles are further finished by receiving a coat ofpaint or varnish by means of rotary paint-brushes J J, adjustable uponand turning with the shaft P, which is adjustable vertically by means ofthe threaded hangers ssand the check-nutn. The lower circumferences ofsaid brushes dip in a receptacle containing the mixture to be applied,while their upper portions eomein contact with the spools or otherarticles, S, carried by the drum A and rotated by the belt K K K K.After receiving the coat of paint the articles S are carried by thefurther revolution of the carrier A to the point t, Fig. 1, where theymay be allowed to drop into some convenient receptacle or removed byhand'and placed in position to dry.

Some articles, as handles, bobbins, 850., can be more convenientlyfinished when placed upon the mandrels Z) b, as shown at Z), Figs. 4 and5. Said mandrels receive a rotary motion by the action of the belt K K KK upon the rollers a a. (See Fig. 5.) When finishing bobbins upon saidmandrels, a pulley, G, is fastened to the shaft L, and another pulley,G, pivoted at 0 below G, and in such position that a band, I, passingaround said pulleys and covered with some erosive material, will come incontact with said articles and smooth their surfaces.

After being smoothed by the band l the bobbins or other articles mayreceive a coat of paint, as described for spools, and'shown at J, Fig.4.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a machine for finishing spools, bobbins, and other like articles,the revolving drum or carrier A, having enlarged heads H H, withanti-friction rolls h 71, set in their circumferences for receiving,supporting, and carrying the articlrs to be finished, substantially asset forth.

2. The work-rotating frictionbelt K K'K K, arranged to partly encirclethe drum A and impart rotary motion to whatever articles may be placedupon the anti-friction rolls h h of the drum A, substantially as shown.

3. The combination of the revolving drum or carrier A, havingwork-supporting antifriction rolls h, fixed in the circumferences of itsenlarged ends or heads, with the work-rotating belt K K K K, as shownand described.

4. The drum or carrier A, having enlarged ends or heads H H, withrollers a a set between them at equal intervals, said rollers beingarmed with bobbin or other work-carrying spindles or mandrels, (seeFigs. 2 and 3, b 1),) substantially as shown.

5. The revolving drum or carrier A, havingrollers a a, armed with bobbinor other worle carrying spindles or mandrels b b, in combination withthe worl -rotating friction-belt K K K K, essentially as described.

6. In machines for finishing spools, bobbins, and other like articles,the smoothing wheels or rubbers E E e e, or the smoothingbelt Z, incombination with the revolving drum A, furnished with anti-frictionrollers h h, or armed with projecting spindles or mandrelsb b, and thework-rotating belt K K KK, as and for the purpose set forth.

7. In an apparatus for painting spools, bobbins, and other likearticles, the revolving paint brush or brushes J, in combination with arevolving drum or carrier, A,provided with anti-friction work-supportingrolls h h, or armed with work-supporting spindlesb b, and thework-rotating friction-belt K K K K, substantiall y as shown anddescribed.

8. In an apparatus for finishingspools,bobbins, or other like articles,the combination of the revolving drum or carrier A, furnished withwork-supporting anti-friction rollers hh, or Work-supporting spindles ormandrels I) b, the device for rotating the articles while beingfinished, the device for smoothing said articles, and the device forpainting them after they have been smoothed, substantially as shown, andfor the purpose set forth.
